I agree completely with what Ryan said, gotta be careful not to repeat and babble.

My problem of eating in public is:
"OMG they're all looking at me eat like a friggin' pig" Blah blah blah then into the whole ED thinking skit. Pretty different then yours, but I think it's still close enough.

You know, my friend is kinda an oinker, but she's odd about eating in public. She tells people though, she's not not eating, she just doesn't eat in public.

Going all day not eating isn't a generally healthy thing to do, maybe you should try grabbing small healthy snacks to eat that won't grab attention, and stuff. Have foods pre-made in the fridge to grab quick so they won't see you cook, etc.

There's nothing wrong with it, it's not some huge psych problem I think, just a little anxiety of it. Try to find a way to keep feeding your body though, around the uncomfort. <3 <3 Good luck.
